Iv y present invention aims to provide a simplified and improved structure for carrying and presenting tuft yarns for insertion between warps in thecourse of weaving, being particularly useful 1n connection with moquette or tuft pile fabric looms, such as AX- ininster carpet looms. In certain respects the present invention is an improvement upon that disclosed and claimed broadly in the patent to Bliiby and Lea 1,590,169, dated June 22, 1926.

. Referring more particularly to the drawings and first to Figs. 1 to 5, the tuft yarn carrier or so-called tube-frame comprises the main longitudinal or s pporting element 1 or carrier proper, shewn as a substantially polygonal tube, bar or frame formed of metal, t which may be otherwise constructed or be of other material; for example, a wooden bar. Said carrier frame 1 is of a length to rceeive and. support along it one more tuft yarn spools 2, depending upon the conditions, particularly the width of the work in connection with which the carrier is to be empl d. It is provided with any usual or preferred means such as the bearing 1828. Serial NO. 299,916.

member 3 for rotatably supporting the spool pintle 4. Similar spool-supporting means is provided at each end of the carrier, and where a plurality of spools are to be mounted, intermediate means are positioned at the adjacent spool ends for rotatably supporting them thereat. Suitable means such as chain engaging member 5 and the hook latch 6 are also provided at the ends of the carrier, for connecting it with the carrier chain of the loom whereby succeeding carriers with their yarn supplies may be presented in the loom in the customary manner.

For the purposes of description, hereinafter the face or portion of the carrier across which the yarns 7, 7, etc., extend from their spool or spools will be referred to as the front, seen at the left in Fig. 2, and the face or portion of the carrier at an angle thereto and below it, as positioned in Fig. 2, will be termed the bottom.

Extending longitudinally of the carrier and at or adjacent its front face I have provided means for receiving and holding in spaced relation said individual yarns, units or groups of yarn strands 7. In the illustrative embodiment of Figs. 1 to 5 said yarn spacing element, spacer or separator comprises a plate or strip 9 secured to the carr er frame 1 and having aportion projecting laterally beyond the front face of the latter. Said projecting portion of the yarn spacer 9 is provided with a series of properly spaced formations, openings or apertures 10 each to receive and position one yarn or yarn unit 7 in the BiXby and Lea patent above mentioned there is disclosed a series of yarn spacing apertures having circuinferentially continuous or closed walls, necessitating the placing of the yarns by threading them in the direction of their length, whether such lengthwise threading is effected manually or mechanically. In accordance with my present invention, however, the yarn spacing element or spacer 9 at the front of the carrier may be so constructed as to provide for the positioning of the yarns in the receiving formations 10 by a broadside or sidowise threading operation, whereby the entire yarn series or any units thereof may be threaded or re- .readed, manually or otherwise, either beore or during actual weaving operations, ovel means also being provided for retaining re yarns in their spaced or threaded relation. It will be understood in this connection I as by stamping or shearing the material of the front edge of the spacer to provide the deflected or off set portions, teeth or barbs 12. In so forming the latter no stock or substantially no stock is cut away at the looking portions or barbs proper 13 of the teeth 12. Due to this construction a yarn or yar unit 7 once positioned in its receiving formation or opening 10 can not escape sideways therefrom, unless kinked or bent laterally about the corresponding locking portion 13 of the spacer. The outer portions of the ceth 12 are desirably inclined as indicated at 14 whereby each yarn or yarn unit 7 may readily be entered and guided sideways into i s receiving formation or opening 10, but cannot reversely escape therefrom for the reason stated.

In conjunction with said novel side-threading yarn spacer 9 for the carrier or tubeframe, I preferably provide adjacent yarnseparating and gripper guiding means herein comprising a series of transverse separators, guides or wall-forming members 15. These latter are desirably removably connected with the carrier and associated with the parts thus far described either in groups or individually, being preferably so related to the described yarn spacer as to cooperate therewith in positivoly retaining the yarns against accidental disengagementfrom the yarn receiving and spacing format-ions or openings 10. In accordance with the invention, said yarn-separating gripper guides 15 are positioned and attached through the medium of a longitudinal strip or strips itself or themselves connected to, removably or otherwise, or formed as parts of the carrier bar proper or frame 1.

In the illustrative embodiment of Figs. 1 to 5 said attaching means for the yarn-sep- 1 arating gripper guides 15 comprises a strip or plate 16 extending lengthwise the carrier throughout substantially the full length thereof either as a single member or as a plurality of shorter units. Said attaching strip 16 is positioned flatwise at the bottom of the carrier and herein immediately beneath the yarn spacer 9, the latter and said strip 16 being there secured, preferably removably, by any suitable fastening means such as the screw or bolt 17 see Figs. 2 and 3,

extending through accurately located openings in the adjacent face of the carrier frame 1 and releasably engaging the opposite frame wall as by means of the lock-nut 18. To insure accurate registration of the attaching strip 16 and the yarn spacer 9 with the carrier frame, the edges of the fastener-receiving apertures or recesses in the attaching strip may be upset as indicated at 19, Fig. 2.

The yarn-separating guides 15, as best seen in Figs. 2 and 5, each comprises a preferably metallic blade, strip or the like of a length to extend approximately from the outer edge of the yarn spacer 9 sufliciently toward the rear of the carrier to be engaged with the attaching strip 16 and insure accurate retention of the guide. In the form of the invention as illustrated in Figs. 1 to 5, the attaching strip 16 is formed with a depending flange 20 at its forward portion, which flange is provided with a longitudinal series of formations, slots, notches, perforations or the like 21 generally corresponding in outline to the cross-sectional form of the individual guides 15. The several guides are positioned in and by the corresponding formations 21 and are secured, preferably removably, in such position by suitable means such as the locking bar or pin 22 extending through an opening provided for the purpose in each guide and so located as to bring it into or substantially into contact with the inner face of the flange 20 when the guides are in proper position, thereby preventing their disengagement toward the front of the carrier.

Additional securing means preferably is provided rearwardly of the flange 20. In the form of Figs. 1 to 5 the guides 15 are formed at their inner or rear ends with a. tail or nib 23. A look strip 24 is secured to the rear of the carrier as by the screws 25 tapped into the adjacent wall, riveting or otherwise, said lock strip having a forwardly or inwardly projecting lip 26 notched along its forward edge as at 27 to receive the inner or rear ends of the respective guides 15; see particularly Fig. 3. As best seen in Fig. 2 the tails or nibs 23 of the several guides are held between said lip 26 of the lock strip and the under face of the attaching strip 16. The guides are thus retained against movement in any direction, but may readily be removed, individually or in groups, upon withdrawal of the locking pin 22.

It will be noted by reference to Figs. 1, 3 and particularly Fig. 4, that each guide 15 is so positioned with relation to the adjacent yarn-receiving formation or opening 10 of the spacer 9 that it covers the yarn entrance passage 11 leading to that formation or opening, including particularly the inner end of said passage, so that a portion of the guide overlaps or lies across the exit of each opening 10, as indicated at 28 in Fig; 4.

The described construction and arrangement alfords a positive bar to escape of the yarns through the side-threading entrance passages 11, necessitating a further lateral deflection or kinking of any yarn before it could enter the inner end of the corresponding passage 11 in addition to that necessitated by the deflected construction of the yarn spacer teeth or barbs 12. Thus each yarn or yarn unit 7 when once positioned in its receiving formation or opening lOis both prevented from working out toward or into the exit passage and also from escaping through said exit passage should it work into it in any manner; each yarn or yarn unit is thus positively locked in spaced or threaded position upon the carrier.

The series of yarns or yarn units 7 coming from the spool supply extend through the spacing formations 10 of the spacer 9 and downwardly between two adjacent guides 15. The latter not only function as ya rn-separating and guiding elements in conjunction with the spacer 9 but also serve as guides for the yarn enga ing means or grippers G of the loom. The flange 20 is located suiliciently rearwardly of the yarn ends to afford proper operating space for the gripper noses, as clearly seen in Fig. 2. Each yarn or yarn unit and its gripper are thus enclosed and guided upon three sides, laterally by the guides 15 and rearwardly by the flange 20. To prevent accidental withdrawal of the yarn ends lengthwise from the formations 10, the latter may be formed with roughened or burred edges or otherwise to engage frictionally with the yarn received by it.

Referring now to the remaining figures of the drawings, there are illustrated certain modifications embodying the general broad combination of the present invention. In considering each of Figures 6 to 14, inclusive, parts not otherwise mentioned may be considered as similar to the corresponding parts as shown in Figs. 1 to 5.

In Fig. 6 the yarn spacer 9a is similar to that of Figs. 1 to 5 but terminates forwardly of the rear wall of the carrier frame 1. The yarn-separating guides 15a are of corre sponding length and are formed with projections or tenons 29 at their rear ends. The attacliing element or strip 16a is in this instance provided with front and rear depending flanges 20a and 30, respectively, the latter having notches, openings or other formations for the reception of said tenons The portions of the rear end of each nide 15a above or below its tenon abuts the inner face of therear flange whereby, in

3 conjunction with the locking pin 2264, the

guide is locked releasably in position. In this as we l as in all. succeedi g'figures the broadside-threading yarn-receiving portion spacer is similar to that of the spacer s. 1 to 5. It is also noted that in any form having a tubular or hollow carrier frame the latter may be suitably reinforced interiorly, for example, as disclosed and claimed in my prior Patent 1,545,464, dated July 7, 1925.

Referring to Fig. 7 the yarn spacer or yarn spacing element 9?) is herein formed integrally with the carrier frame 1?), comprising a lateral extension of the under wall of the latter. The yarn-separating gripper guides 15?) and their attaching element 16?) may be the same as in Fig. 6.

In the further embodiment of Fig. 8 the carrier frame 1 is polygonal and tubular in the form of Figs. 1 to 5 and Fig. 6, but the yarn spacing element 90 is formed integrally with the guide attaching element 160. The front flange 200 of the latter comprises a doubled strip substantially as illustrated, the yarn spacer 90 being an angular forward extension therefrom. The attaching element or screw 17 is located intermediate the two flanges of the attaching strip 160 as in the previous modifications of Figs. 6 and 7.

In Fig. 9 the yarn spacer 9d and the attaching strip 16d are likewise integrally formed, as in Fig. 8, but the guide engaging portion of the latter is reversed. The horizontal portion of the strip 16d intermediate the flanges 20d and 31, respectively, is at the bottom of the attaching strip and the securing means or bolts 17d are located forwardly of the forward flange 20d.

In the further modification of Fig. 10 the carrier frame 16 is partially open and is formed with integral downward extensions 32, 33, respectively, constituting flanges for receiving and locking the yarn-separating gripper guides 15@ similarly as in the previous figures. The yarn spacer 90 is formed with a flange 34 secured to the frame 10 as by the transversely extending bolt or screw 176.

In Fig. 11 the guide attaching strip 16; and the guides 15; are similar to those of Figs. 6 and 7. The carrier frame 1f in this instance is composed of a plurality of parts, a main part 35 forming three walls and a supplemental part 36 forming a portion of the bottom wall. The two parts are folded together or otherwise interconnected at' their adjacent edges as at 37. The yarn spacer 9f is formed as an integral forward extension of said supplemental part 36 of the carrier frame.

In the modification illustrated in Fig. 12 the carrier frame is in the form of a wooden bar 19 to the bottom of which is attached, as by wood screws 38, aguide attaching strip 169 which may be similar to that of Figs. 6, 7 and 11, and to the forward portion of which is attached a yarn spacer 99 as by means of a flange 39 and wood screws 40.

According to the further embodiment of Fig. 13 the carrier frame 1h has its forward wall downwardly extended and doubled back upon itself to provide a guide-receiving flange 2072, and is bent angularly outwardly to form a yarn spacing element 9h. At their rear ends the yarn-separating gripper guides 15h engage an inturned portion 41 of the carrier frame, being there held in any suitable manner, as for example, by soldering as indicated at 42.

In the form of Fig. 14 the attaching strip or member 162' comprises but a single flange 520i similarly as in the form of Figs. 1 to 5 but is formed, as illustrated, integrally with the yarn-separator 92'. Each yarn-separating gripper guide 152' is provided at its rear end with a head 43 and in this instance is inserted through the flange. 202' from the rear thereof, being held against rearward displacement by suitable locking means such as the spring clamp 44 held in position upon the carrier frame in any suitable manner as indicated, for example, at 45.
